This forum is NOT FOR DUMMY USERS questions or problems but DEVELOPER.After upgrading to 3011.0, I was pleased that all of my channels and setting stayed, and PVR still worked. However, SamyGO would not boot and ruSamsungTVCommunicator wouldn't connect. Since that was unacceptable, I downgraded to 3005.1. I'm pleased to report that the 0000 firmware worked easily. Otherwise I would have been out of luck since the TV was no longer rooted. One annoying thing is that the 0000 firmware wipes out all settings, but at least the TV works! Once I downgraded to 3005.1, everything worked again except for ssh and ruSamsungTVCommunicator. My cifs mounts were fine, and ftp to the TV was fine too.
Since I could change firmware easily now, I tried 3009.2 and 3011.0. On both of those the mount script on the USB does not run. When I downgrade to 3005.1, it does run. I tried a simple script with just an echo command so I know it's nothing in the script that blocks it. I like using ext3 on my USBs so I can have symbolic links, but I confirmed that the behavior is the same with fat. Also, it behaves the same with hotplug and coldplug. So, without re-rooting, runs the mount script, while 3009.2 and 3011.0 do not.
I think that my next step will be to reformat the rw area in the TV, and try the hotel mode hack on 3011.0. But I thought I would write this to see if anyone has thoughts about this.
Here is my /mtd_rwarea/usb_mount/usb_hotplug.sh file

I figured out the problem with ssh was due to my own mixup with ip addresses and passwords. The problem with why ruSamsungTVCommunicator stopped working I didn't figure out, but I upgraded from v 4.13 to 4.18 and it's working now. I plan to try changing firmware again before messing with hotel hack.
update:
I tried the update again, and it looks to me like the script /mtd_rwarea/usb_mount/usb_hotplug.sh really does not execute in 3011.0. I put some echo s in it, and they don't show. However, when I return to 3005.1, the script is still there, and works fine. It looks to me that the widget hack does not survive an upgrade to 3011.0.
update:
I realized that I could use ftp and ssh to put files into /mtd_rwarea/usb_mount without going through all of the complexities of the Hotel mode hack. So since I already had rooted 3005.1 via Widget hack, I created the following files.
/mtd_rwarea/usb_mount/usb_cmd:
Code: Select all
#!/bin/sh
if [ "$1" = "mount" ] ; then
if [ -f /dtv/usb/$3/mount.sh ] ; then
sh +x /dtv/usb/$3/mount.sh
fi
fi
/sbin/usb_mount/usb_cmd $1 $2 $3 $4 $5 $6 $7
Code: Select all
#!/bin/sh
/sbin/usb_mount/usb_mount $1 $2 $3 $4 $5 $6 $7
Code: Select all
-rwxr-xr-x 1 root 0 328 Jan 1 1980 usb_cmd
-rwxr-xr-x 1 root 0 4331 Jan 1 1980 usb_hotplug.sh
-rwxr-xr-x 1 root 0 120 Jan 1 1980 usb_mount
Now, I modified the USB to contain mount.sh:
Code: Select all
#!/bin/sh
BASEDIR="${0%/*}"
$BASEDIR/.SamyGO/rcSGO $BASEDIR/.SamyGO >/dev/null 2>&1 &
What's particularly interesting about this method, is that it can be used to root any firmware version without using the Import/Export channel list portion of the Hotel mode hack. For example, to hack 3011.0, use the 0000 firmware to downgrade to 3005.1, root via Widget hack, copy the files I described above, and then upgrade back to 3011.0.
. I did stupid mistake. I was uploading files from windows system and didn't upload these 2 in asc mode. Auto detection failed of course, because there is no "sh" extension. So I had to update widget hack code to delete also these new 2 files. Afterwards TV's USB was working again. Then I did correct upload, manually tried to execute those files to be sure and removed usb_hotplug.sh. After TV restart everything worked! So I did upgrade to latest firmware for my UE55C6500 and hack is working 
. Hopefully Samsung will not "fix" also this
